I work in Convex Optimization, and I look for any function like a Python’s Chordal Matrix Package.  
Are there something like that in JuliaLang?

There are three.

- [CliqueTrees.jl](https://github.com/AlgebraicJulia/CliqueTrees.jl)
- [Chordal.jl](https://github.com/tjdiamandis/Chordal.jl)
- [ChordalGraph.jl](https://github.com/wangjie212/ChordalGraph)

I have been working on the first one!
